DETAILED DESCRIPTION OF PREFERRED EMBODIMENT

[0041] While the present invention will be described more fullyhereinafter with reference to the accompanying drawings, in which apreferred embodiment of the present invention is shown, it is to beunderstood at the outset of the description which follows that personsof skill in the appropriate arts may modify the invention here describedwhile still achieving the favorable results of this invention.Accordingly, the description which follows is to be understood as beinga broad, teaching disclosure directed to persons of skill in theappropriate arts, and not as limiting upon the present invention.

[0042] Illustrative embodiments of the invention are described below. Inthe interest of clarity, not all features of an actual implementationare described. It will be appreciated that in the development of anyactual embodiment numerous implementation-specific decisions must bemade to achieve the developers' specific goals, such as compliance withsystem-related and business-related constraints, which will vary fromone implementation to another. Moreover, it will be appreciated thatsuch a development effort might be complex and time-consuming, but wouldnevertheless be a routine undertaking for those of ordinary skill havingthe benefit of this disclosure. Additionally, the embodiments disclosedcan be combined, in accordance with the principles of the presentinvention, to form an embodiment that enhances the benefits of thepresent invention.

[0043]FIG. 1 is a view showing a security system employing a switchingunit. Referring to FIG. 1, the security system employing the switchingunit comprises a plurality of security cameras 11, a switching unit 12,a monitor 13, and a recorder/reproducer 14.

[0044] The switching unit 12 selectively receives image signalstransmitted from the plurality of security cameras 11 in accordance witha sequence of set up, and outputs the image signals. The monitor 13displays the image signals transmitted from the switching unit 12, andthe recorder/reproducer 14 records the images received through theswitching unit 13 into a recording medium. The recorder/reproducer 14has a plurality of keys to set up recording and playing the imagesrecorded in the recording medium.

[0045] This security system employing the switching unit is establishedby contacting the switching unit 12 and the recorder/reproducer 14 whichare exclusively used for the security system employing the switchingunit to the monitor 13 and the security cameras 11. However, eachproduct is expensive because they are supplied to be exclusively usedonly for the security system. Thus, only some users, who have a greaterneed to watch and secure the building that justifies the expenses forinstalling the system, purchase the security system. Consequently, it isdifficult to lower the cost needed to establish the security systememploying the switching unit, and the cost has become an obstacle toobtain a plentiful supply of users.

[0046] Most office-working environments have been changed to usecomputers for accomplishing jobs, and also the use of computers, whichenable Internet communication at home, has been widely increased. Yet,if the monitor 13 and the recorder/reproducer 14 among the securitysystems are installed in a working place with the electric devices, thepractical usage rate is deteriorated, since some places for installingthe devices should be allocated there. Moreover, when using otherdevices, the devices might have to be moved to change their positions.

[0047] Hereinbelow, the preferred embodiment of the present inventionwill be described in great detail by referring to the appended drawings.FIG. 2 is a view schematically showing a security system employing amultichannel image processor, in accordance with the principles of thepresent invention.

[0048] Referring to FIG. 2, the security system includes a multichannelimage processor 30 and a user's computer 50. The computer 50 includesmonitor 54, keyboard 55 b, and mouse 55 a. The multichannel imageprocessor 30 is connected between a plurality of cameras 20 forphotographing and the user's computer 50.

[0049] The multichannel image processor 30 selectively processes signalstransmitted from the plurality of cameras 20 in accordance with acontrol signal transmitted from the user's computer 50, 5 transmits theprocessed signals to the users' computer 50, and controls driving of theplurality of cameras 20. Preferably, the multichannel image processor 30is one piece to be installed outside.

[0050] Moreover, it is preferable that the multichannel image processor30 has separated input channels for receiving input signals and channelsfor communicating data to control the plurality of cameras 20 in regardto the plurality of cameras 20. A wireless communication or acommunication by wire can be used for the data communication, and it ispreferable that the data communication by wire applies an RS-485interface mode, which has a little decay rate for a long distance.

[0051] A more detailed description will be done hereinafter by referringto FIG. 3. The FIG. 3 is a block diagram showing one preferredembodiment of the multichannel image processor of FIG. 2, according tothe present invention. Referring to FIG. 3, the multichannel imageprocessor 30 a has an input channel port 31, a plurality ofanalog-to-digital (A/D) converters 33, a coding unit 37, a centralprocessing unit (CPU) main controller 39, a memory controller 41, anRS-232 interface (I/F) module 43, and an RS-485 interface (I/F) module44.

[0052] The input channel port 31 has a plurality of input channels 31 a1, 31 b 1, 31 c 1, and 31 d 1 disposed therein in order to receivesignals transmitted from the plurality of cameras 20 a, 20 b, 20 c and20 d.

[0053] Preferably, each input channel (IN) 31 a 1, 31 b 1, 31 c 1, and31 d 1 have output terminals (OUT) 31 a 2, 31 b 2, 31 c 2, and 31 d 2,which are branched off from the input channels 31 a 1, 31 b 1, 31 c 1,and 31 d 1 to output the image signals transmitted from the cameras 20as signals for separate apparatuses by branching off the signals.Numbers Ch1 through Ch4 is given for more convenient description forimage output line of each camera 20 a, 20 b, 20 c, and 20 d.

[0054] Only four input channels 31 a 1, 31 b 1, 31 c 1, and 31 d 1 areshown to avoid the complication of the figure, but the number of inputchannels can be extended. The A/D converters 33 a, 33 b, 33 c, and 33 dare disposed for each input channel 31 a 1, 31 b 1, 31 c 1, and 31 d 1,and convert transmitted analog signals into digital signals. The A/Dconverters 33 can be omitted, when the multichannel image processor 30 asupports a digital camera.

[0055] The memory 35 temporarily stores the image signals transmittedfrom the input channels disposed corresponding to each input channel 31a 1, 31 b 1, 31 c 1, and 31 d 1. The memory 35 can be called a framebuffer.

[0056] The memory controller 41 selectively controls the memory 35 inaccordance with a channel control signal, and outputs the memory to thecoding unit 37. In other words, if it is a four-division display mode,the memory controller 41 controls the memory 35 so that the datatransmitted to the memory 35 of each channel can be consecutively outputfor each frame, and if it is a single mode, the memory controller 41controls the memory 35 to continuously output only the data transmittedto the memory 35 of selected channels.

[0057] The coding unit 37 encodes the image signals output from theselected memory 35, and outputs the coded signals through a video2-output port 47, which is an image output terminal for the user'scomputer 50. The encoding method of the coding unit 37 can apply variousmethods, for example, it can be a method of separating the data forcolors and encoding the data.

[0058] A multiplexer 45 disposed between the each input channel 31 a 1,31 b 1, 31 c 1, and 31 d 1 and video 1-output port 46 in order toconsecutively switch the input channel 31 a 1, 31 b 1, 31 c 1, and 31 d1 in accordance with a set-up order. Here, the video 1-output port 46 isa terminal for transmitting an image generated by being switched in turnfor the channels by the multiplexer 45 to another external apparatus ordisplayer (not shown) different from the user's computer 50. Therefore,the video 1-output port 46 can be used when the user wants to divide theimage transmitted from the plurality of cameras 20 into four on a screenof the display device in a working circumstance different from theuser's computer 50.

[0059] An alarm sensor 60 can use each kind of sensors known as sensorsfor sensing an abnormality in the region of the object to be watched ofthe cameras 20. For example, a contacting or non-contacting sensor forsensing the opening/closing of a door, a heat sensor using heat sensingmethod for sensing the entrance of a person, a motion sensor detectingmotion of a person, and a piezo-electric sensor for sensing the damageor shock by being attached on a window can be applied as the alarmsensor 60. In addition, an infrared sensor, a magnetic sensor, etc. canbe applied as the alarm sensor 60 according to the attribute of theobject being watched.

[0060] A user can utilize the present invention to designate (or select)one or more cameras to be associated with a particular alarm sensor.Then, when that particular alarm sensor is activated, video images fromthe designated camera or cameras can be automatically recorded anddisplayed. The locations of the designated cameras is independent of thelocation of the alarm sensor. Thus, the designated cameras can bephysically near the region of the alarm sensor, or the designatedcameras can be physically distant from the region of the alarm sensor.

[0061] For example, if a first alarm sensor is set to detect when animportant door opens, a user can select three cameras to be associatedwith an alarm signal from that first alarm sensor. The three camerascould include a first camera positioned to allow a user to view a frontside of the important door, a second camera positioned to allow the userto view a back side of the important door, and a third camera positionedto allow the user to view any people who travel down a hallway that isnear a room with valuable items, and the hallway is 100 meters from theimportant door. In response to the alarm signal from the first alarmsensor, image signals from those three cameras can be sequentiallyrecorded, or displayed, or recorded and displayed, for a predeterminedamount of time.

[0062] Generally, in accordance with the principles of the presentinvention, one alarm sensor is used for one camera, and thus one alarmsensor is associated with one and only one camera. However, as in theexample described above, multiple cameras can be designated to beassociated with a single sensor, in accordance with the principles ofthe present invention. Thus, the present invention can be set up to havefive cameras (numbered 1 through 5) and ten alarm sensors (numbered 1through 10), for example. Here, the camera number 2, the camera number4, and the camera number 5 can be set to correspond to the alarm sensor7, for example. When the alarm sensor 7 is activated, the images viewedby cameras 2, 4, and 5 can be sequentially displayed and recorded in thefollowing order: camera 2 -> camera 4 -> camera 5-> camera 2-> camera 4-> camera 5-> camera 2-> camera 4 and so on.

[0063] If an abnormality signal is transmitted from the alarm sensor 60,the main controller 39 transmits the abnormality signal receiveinformation to the user's computer 50, and controls the memorycontroller 41 so that a channel can be selected corresponding to analarm channel select mode replied from the user's computer 50 for thegeneration of the abnormality signal.

[0064] The RS-232 interface module 43 communicates data between the maincontroller 39 and the user's computer 50, and comprises a computer datacommunication terminal for connecting. The RS-485 interface module 44supports data communication for controlling the operation of the cameras20 connected with the main controller 39 through the input channels 31 a1, 31 b 1, 31 c 1, and 31 d 1. The RS-485 interface module 44 has acamera communication terminal.

[0065] A reference numeral 42 is an electrically erasable programmableread only memory (EEPROM) having various data including a startingprogram. The cameras 20 comprise an interface module 24, a cameracontroller 21, a camera drive unit 22, and a photograph unit 23.

[0066] The photograph unit 23 converts the signals photographed througha lens into electric image signals, and transmits the electric imagesignals to one input channel selected among the plurality of inputchannels 31 a 1, 31 b 1, 31 c 1, and 31 d 1 through the cameracontroller 21.

[0067] The camera drive unit 22 can drive the photograph unit 23corresponding to supported functions such as pan, tilt, and zoom in/out,and controls the driving of the photograph unit 23 according to acontrol signal input from the RS-485 interface module 44 through thecamera controller 21. In the preferred embodiment of the presentinvention, to avoid the complication of the figure, it has beenillustrated that one camera 20 is connected with the RS-485 interfacemodule 44, but a plurality of cameras 20 can be connected in parallelwith the RS-485 interface module 44, and the communication with theset-up cameras 20 is performed by using an identifier set up differentlyfor each camera.

[0068] When a camera can zoom in/out, this indicates that the camera canzoom in and can zoom out. A zoom operation can include a zoom-infunction or a zoom-out function, or one of those two functions followedby the other. When a camera performs a zoom in/out, the camera can besaid to be performing a zoom operation.

[0069] The cameras 20 communicate data through the RS-485 interfacemodule 44, and the photographed image signals are transmitted to theinput channels 31 through a separate output terminal.

[0070] On the other hand, the multichannel image processor 30 can beconstructed to perform wireless communication with the cameras 20 unlikethe communication method by wire such as the RS-485 interface module 44.

[0071]FIG. 4 is a block diagram showing another preferred embodiment ofthe multichannel image processor of FIG. 2, according to the presentinvention. The elements having the same functions as the elements shownin FIG. 3 are given the same reference numerals.

[0072] The multichannel image processor 30 b comprises a wirelesstransmitter 49 for communicating data between the main controller 39 andthe cameras 20. Moreover, the cameras 20 also have a wirelesstransmitter 25. According to the above construction, the multichannelimage processor 30 b can wirelessly control the movement of the cameras20. A different embodiment of the image processor of FIG. 2 has thewireless capabilities of FIG. 4 and also the non-wireless capabilitiesof FIG. 3. The user's computer 50 is established with the usual computerhardware.

[0073]FIG. 5 is a block diagram showing the user's computer 50 of FIG. 2in more detail. Referring to FIG. 5, the user's computer 50 has acentral processing unit (CPU) 51, a read only memory (ROM) 52, a randomaccess memory (RAM) 53, a display device 54, an input device 55, amemory 56, and a communication device 58.

[0074] The input device 55 includes a mouse 55 a and/or a keyboard 55 b.The communication device 58 includes an RS-232 interface module (notshown) for a serial communication. An image signal input end (not shown)of the user's computer 50 receives image signals from the video 2 outputport 47 of the multichannel image processor 30. It is preferable that avideo graphic adaptor (VGA) card (not shown) be used for processingthose image signals.

[0075] An operating system (O/S) 57, for supporting a window system suchas window 98, window 2000, and linux, is disposed in the memory 56. Amultichannel image driver 70, which is an application program for animage security is installed in the memory 56.

[0076] The multichannel image driver 70 is programmed to process thesignals transmitted from the plurality of cameras 20 by being supportedfrom the operating system 57, and control the multichannel imageprocessor 30 and the cameras 20 in a window system. The multichannelimage driver 70 can be offered in a form recorded in a recording medium,so that the multichannel image driver 70 can be installed in a desireduser's computer.

[0077] The computer 50 uses a windows-based operating system. Someexamples of windows-based operating systems include Microsoft Windows95, 98, ME, NT, 2000, and XP. However, this invention is not limited tocomputers using Microsoft operating systems. There are windows-basedoperating systems other than Microsoft Windows operating systems. Forexample, Apple Computer has utilized a windows-based operating systemfor Apple's Macintosh computer. FIG. 6 is a block diagram showing amultichannel image driver of FIG. 5. As shown in FIG. 6, themultichannel image driver 70 comprises a transmitter 71, a controller72, a display unit 73, and a module support unit 74. The transmitter 71receives the signals transmitted from the multichannel image processor30 through the communication device 58, transmits the signals to betransmitted from the controller 72 to the multichannel image processor30 through the communication unit 58.

[0078] The module support unit 74 comprises various operation modulesfor offering a main frame when the multichannel image driver is operatedand screens loaded corresponding to the selected key, and performing afunction corresponding to an offered menu by being controlled by thecontroller 72.

Thedisplay unit 73 displays information about an object to be displayedthrough the display device 54 by being controlled by the controller 72.

[0079] Hereinafter, the operation of the multichannel image driver 70will be described in greater detail by using a screen offered when themultichannel image driver 70 is operated.

[0080]FIG. 7 is a view showing a main frame displayed by a multichannelimage driver of FIG. 6 through a display device. The main frame isoffered through the display device when the multichannel image driver isoperated. Referring to FIG. 7, the main frame 80 is displayed on ascreen 54 a of the display device 54. The main frame 80 comprises a mainimage display window 81, and a manipulation window having a plurality ofkeys displayed in regions plurally divided.

[0081] The main image display window 81 is a window for displayingtransmitted image information as four-divided screen or as one screen inaccordance with a display mode. The manipulation window comprises afirst key box 100 disposed at a lower end, and a second key box 110disposed at a right side. The keys in the key boxes 100 and 110 are usedto select features of the security system.

[0082] A power key 101, disposed at the first key box 100, is used whenunloading the screen, which means finishing the operation. The power key101 is a key for performing the same function as the close buttonillustrated at reference numeral 85, which is a familiar feature in thewindow system.

[0083] A stop key (STOP), a record key (REC), a rewind key (REW), a playkey (PLAY), a fast forward key (F.F), and a pause key (PAUSE) are allwell-known keys, and the description about the function of these keyswill be omitted. The features associated with these keys are well known.

[0084] An open key (OPEN) 103 is a key to be used when reproducing arecorded file. When the open key 103 is selected, the controller 72controls the module support unit 74 so that the desired file is easilyselected, and loads a file select support window 303 as shown in FIG.11. FIG. 11 is a view showing a module offered by being loaded when anopen key of FIG. 7 is selected. The file select support window 303offers a condition select menu 305, and a record file list displaywindow 307 for listing up the recorded files in accordance with aselecting condition.

[0085] The condition select menu 305 includes a menu for selecting thetype of the recorded image file (an alarm record, a user record, and acamera number select window), and a menu for setting a date section ofthe image file that the user wants to find. Here, the alarm record is animage file recorded when the alarm mode is operated, and the user recordis an image file recorded when the user pushes a record key. The cameranumber select window is a window to be used when looking up recordedfiles only corresponding to the entered camera number.

[0086] A look-up key 306 searches files corresponding to the selectedmenu from the memory 56, and lists the searched files. The record filelist display window 307 has a window for supporting search of a folder,and a window for listing up the recorded file according to the selectedcondition. Preferably, the list offers information on the filescorresponding to listed items such as a record date, a record mode (analarm mode and a user mode), a camera number, a fps (frame per second)value, and a file name. The file name is automatically created when theuser pushes the record key, or when recording for a predetermined timeis automatically performed by being judged by the alarm mode.Preferably, the file name is named so that the user easily recognizesrecording information, for example, the record date, the camera number,the record mode, and a coding method, etc., through the file name. Forexample, if an image of a camera number 5 recorded Jul. 4, 2001 p.m. 11o'clock 47 minutes 14 seconds is a file of the first screen recorded asa Joint Photographic Experts Group (JPEG) method as the user selects therecord key, the controller 72 creates the file name as20010704134714_CAM05_user_(—)01.MJPEG. In the above file name, for afile name recorded by the alarm mode, the part addressed as user isreplaced by alarm, which shows that the file is recorded by the alarmmode.

[0087] According to the above method for creating, naming, andsupporting to read files of the multichannel image driver 70, the usercan find an image that he/she wants to see without any difficulty, andthe time for searching files will be decreased.

[0088] Referring back to FIG. 7, the second key box 110 has a window forinputting the number of a camera, and a key (SEL) for selecting when theuser wants to see the image of the camera corresponding to the inputcamera number. If the SEL key is selected, the multichannel image driver70 processes the image transmitted from the camera of the input numberto be displayed on the main image display window as a full screen.Reference numeral 111 is a system set-up key.

[0089]FIG. 8 is a view showing a set-up module window offered by beingloaded when a system set-up key of FIG. 7 is selected. FIG. 8 is a viewshowing a system set-up module window, which is loaded by beingsupported by the module support unit 74, when the system set-up key 111is selected. As shown in FIG. 8, the system module set-up window 211offers menus for selecting a communication set-up 220, a camera set-up230, an alarm set-up 240, and a video set-up 250. The window 211 isdisplayed when the set-up mode is selected or requested. The set-up modeis selected or requested when the set-up key 111 is selected.

[0090] The communication set-up menu 220 offers a menu for setting up aport to communicate with the multichannel image processor 30. The cameraset-up menu 230 offers a menu for setting up one number in the rangefrom 0 to 255 of the plurality of cameras 20 connected with the inputchannels of the multichannel image processor 30. The camera set-up menu230 offers also a menu for setting up a sequence maintenance time foreach channel adjustable in one-second increments, from one second to 30seconds. The range of numbering the cameras and selecting the sequencemaintenance time is not limited to the above-mentioned preferredembodiment. The alarm set-up menu 240 offers a menu for setting up analarm mode operation time to consecutively record and display on thecorresponding cameras 20, when an alarm signal is transmitted from themultichannel image processor 30.

[0091] The video set-up menu 250 offers a menu for setting up adirectory to record the image 21 displayed through the image displaywindow 80, and a disk limit alarm item for setting up to alarm when theremaining capacity of the memory 56 reaches a certain percent of theentire capacity. The video set-up menu 250 also offers a menu forstopping the recording, when the memory capacity reaches the set-upaimed capacity set through the disk limitation item, or for compressingand storing the image with set-up coding method, for example, JPEG,wavelit, or Moving Picture Experts Group (MPEG).

[0092] For one example, the memory capacity, consumed by time inaccordance with the number of frame per second and the attribute of theimage data in regard to the degree of the movement, a NationalTelevision Standards Committee (NTSC) method and a phase alternatingline (PAL) method are shown in FIG. 12A and FIG. 12B, when the codingmethod for the record is set up as the motion JPEG coding method. FIG.12A is a view showing a memory capacity consumed when image data isrecorded into a record device using National Television StandardsCommittee (NTSC) method by a multichannel image driver of FIG. 6 for atransmitted image. FIG. 12B is a view showing the memory capacityconsumed by time when image data is recorded into a record device usingphase alternating line (PAL) method by the multichannel image driver ofFIG. 6 for the transmitted image.

[0093] The recordable time is for the remaining capacity in the entirecapacity of the memory 56 can be calculated by setting up a basic datafor the memory capacity per frame based on the basic data.

[0094] In addition, the video set-up menu 250 has a window for settingup a frame capture rate per second and for displaying a recordable timein the memory 56 when applying the present record rate, and for settingup the storing date of the recorded files.

[0095] Referring back to FIG. 7, if one key among four camera selectkeys located next to the system set-up key 111 is selected, the selectedkey processes the display mode for displaying the image of only thecorresponding camera 20. Reference numeral 116 is a key for dividing theimage display window 81 into four and displaying the image transmittedfrom four cameras 20 after dividing the image into four. Referencenumeral 117 is a key for consecutively displaying the image signals as afull screen on the image display window 81 for the order of the camerascorresponding to the set-up pattern. Reference numerals 118 through 121are keys for setting up a mode for displaying the image after freezingthe image of the corresponding cameras in the four-divided display mode.In other words, if the reference numeral 119 is selected, the images ofthe camera numbers 1, 3, and 4 are consecutively displayed in regard tothe transmission to the divided regions corresponding to thefour-divided screens, and, in the image displaying region for the cameranumber 2 among the four-divided screens, the present image of the cameranumber 2 is frozen and continuously displayed. Reference numeral 122 isa key for using when lifting the alarm mode operated in accordance withthe transmission of the alarm signal.

[0096] Reference numeral 130 is an az imuth marking window, and there isazimuth guide information such as up, down, right, and left displayedtherein for guiding the photograph adjust direction based on a roundpoint in the center.

[0097] A ball mark 131 indicated as a ball type at the round point inthe azimuth mark window 130 is a photograph direction manipulation key,and if the key is not selected, the ball mark 131 is placed at the roundpoint.

[0098] The multichannel image driver 70 displays the ball mark 131 inthe azimuth mark window 130 by moving the ball mark 131 in accordancewith the drag direction of the mouse 55 a clicked to select the ballmark 131, and outputs a rotation control signal including acorresponding movement coordinate information for rotating acorresponding camera (selected by a key among the camera select keyssuch as 112 through 115 and the SEL key) in accordance with thedirection of the movement to the corresponding camera 20 through themultichannel image processor 30.

[0099] When the click status of the mouse 55 a is released, the ballmark 131 is returned to the round point. Therefore, the user can easilyadjust the photograph direction of the cameras 20 by manipulating themouse 55 a. The ball mark 131 can be selected by placing the arrowassociated with computer mouse 55 a over the ball mark 131, and thenpressing down the left mouse button 55 c. Then, the ball mark 131 can bemoved in the azimuth marking window 130 in a desired direction by movingthe mouse 55 a in a corresponding direction, with the left mouse button55 c continuously held down. Thus, the ball mark 131 is dragged in thedesired direction. In this way, a camera's viewing direction can beeasily modified. When the left mouse button 55 c is released, the camerastops moving, and the ball mark 131 returns to the center of the azimuthmarking window 130.

[0100] Keys disposed next to the names of focus, zoom, and iris arebasic photograph manipulation keys, and these keys are for adjusting thefocus, zoom, and iris as understood through the contents (such as far,near, wide, tele, open, and close) written under these keys.

[0101] The window associated with reference numeral 140 is a scale bardisplay window for displaying recorded capacity of the memory 56. Thewindow associated with reference numeral 150 displays remaining memorycapacity of the memory 56 and recordable time when recoding with thecurrently set-up record mode.

[0102] On the other hand, when the key associated with reference numeral107 is selected, a succeeding frame is presented, as shown in FIG. 9.The key associated with reference numeral 107 is the next key 107. TheFIG. 9 is a view showing a succeeding frame offered when a next key 107of FIG. 7 is selected. The elements having the same functions as theprevious figures have been numbered as the same reference numerals.

[0103] In FIG. 9, the first key box 100 is replaced by a third key box260, and the rest of the elements are the same as those in the previousfigures. The third key box 260 has a plurality of detailed photographmanipulation keys. The keys in the key box 260 are used to selectfeatures of the security system.

[0104] Let us suppose that main frame 80 and first key box 100 aredisplayed, as shown in FIG. 7. In this circumstance, if the “next” key107 is selected, then main frame 80 is replaced by succeeding frame 180,and also first key box 100 is replaced by third key box 260 (as shown inFIG. 9).

[0105] If the next key 107 is pressed (selected) in a state when theframe 80 is being displayed, the frame 80 will no longer be displayed,and the frame 180 shall then be displayed. Likewise, if the next key 107is selected in a state when the frame 180 is displayed, the frame 180will no longer be displayed, and the frame 80 shall be displayed.

[0106] The third key box 260 is displayed in FIG. 9. The third key box260 includes the menu key 261, the preset key 262, the pattern key 263,and other keys.

[0107] When a user selects the menu key 261 in the third key box 260,the screens that are loaded are: a screen for setting conditions aboutwhite balance, shutter speed, and motion detection function; a screenfor setting a range of angle of auto pan; a screen allowing a user togive numbers to each of the regions divided in regard to the 360° of theazimuth angle and setting zoom in/out according to the numbers given tothe regions (thus setting information required for execution of presetkey 262 and scan key 264); and a screen for setting conditionscorresponding to the execution of the sub-menu key.

[0108] When a user selects the preset key 262 in the third key box 260,there is no additional screen displayed. The number of the camera thatwants the preset mode and the zoom in/out preset set-up numbercorresponding to a desired azimuth angle are selected after selectingthe preset key 262. Then, by selecting an enter key, photographing iscarried out according to the zoom in/out information set at the azimuthangle that corresponds to the selected preset set-up number.

[0109] When a user selects the pattern key 263 in the third key box 260,there is no additional screen displayed. The file name of a filecorresponding to a desired operation pattern (selected from among storedpatterns) is typed into the computer after selecting the pattern key263. Then, by selecting the enter key, photographing is carried outaccording to the operation pattern that corresponds to that file name.

[0110] The user selects pattern information storage items from a settingscreen that is provided through the manipulation of the menu key 261.While adjusting the camera through the basic manipulation keys, theadjustment information about the operational pattern of the camera isstored for a predetermined time period (30 seconds, for example). At thetime of the storage, each item of the operational pattern information asstored is given a name that will identify the same from another. Theuser, therefore, uses the pattern key 263 when he/she wants to view theimage that is taken by the camera repeatedly operated according to acertain one of the stored operational patterns.

[0111] As shown in FIGS. 7 and 9 of one preferred embodiment of thepresent invention, the keys in the second key box 110 are included inthe main frame 80 and the next frame 180, the keys in the first key box100 are included in the main frame 80, and the keys in the third key box260 are included in the next frame 180. However, a window can also bedesigned such that the keys in the first, second, and third key boxes100, 110, and 260 are all included in one frame, although the screenwould become more complex.

[0112] If a menu key 261 is clicked, the menu key 261 supports to set upin advance what is needed to operate the functions of the detailedphotograph manipulation keys that will be described later on.Preferably, the menu key 261 supports to select and set up an identifierfor each camera, white balance, shutter speed, and motion detection. Ifthe menu key 261 is selected, a corresponding module program of themodule support unit 74 is loaded.

[0113] The set-up item supported by the menu key 261 is beingcorresponded to the operation key, which will be described later on, andthe set-up support will be explained using a key also described lateron.

[0114] A preset key 262 is a key for selecting a mode for aphotographing operation, in accordance with preset set-up zoom in/outinformation. The preset set-up zoom in/out information is used by thephotographing apparatus in order to photograph the region correspondingto one ordered number among the zoom in/out preset set-up information,which is set up after being selectively divided by giving numbers toeach region plurally divided in regard to the azimuth angle. The presetset-up information can set up zoom in/out about the 128 regions plurallydivided in regard to the azimuth angle by using the menu key 261 and acorresponding zoom in/out key. The set-up zoom in/out information can bedescribed as set-up zoom information. The preset set-up zoom in/outinformation can be described as preset set-up zoom information.

[0115] If the user wants the camera to photograph with one preset set-upnumber among the preset set-up information, the user selects the presetkey 262, and then inputs the preset set-up number into a number inputwindow below, and clicks an enter key (an arrow is indicated in a box)disposed beside, then the camera is controlled to photograph in the setup zoom in/out status in regard to the azimuth angle of thecorresponding number.

[0116] A manipulation pattern key 263 is a key for operating the camerain accordance with a stored pattern for a certain manipulation of thebasic photograph direction manipulation key. Here, if a pattern memoryis set up using the menu key 261, the manipulation pattern memory storesthe pattern information about the manipulation of the basic photographdirection manipulation key for a predetermined time, 30 seconds.Preferably, whenever storing the manipulation pattern, the menu key 261supports to give an identification number. In this case, as describedbefore, after the manipulation pattern operation key 263 is selected, ifan identification number of a desired manipulation pattern is entered,and the enter key is clicked, the camera is controlled to be operated inaccordance with the stored manipulation pattern.

[0117] A scan key 264 is a key for commanding to sequentially photographregions corresponding to the preset set-up information, according toordered numbers, by using the menu key 261. In other words, when thepreset ordered numbers are set up from 0 to 5, if the scan key 264 isselected, then the scan key 264 controls the camera to photograph theregions corresponding to the ordered numbers from 0 to 5 sequentially byadjusting the zoom in accordance with the corresponding zoominformation. The zoom information can be described as preset zoom in/outset-up information.

[0118] Each one of the ordered numbers corresponds to a region that canbe photographed or viewed by at least one of the cameras. Thus, when thepresent invention is directed to sequentially photograph or view regionscorresponding to ordered numbers 0 to 5, the following steps occur.First the region 0 is photographed/viewed, then region 1 isphotographed/viewed, then region 2, then region 3, then region 4, etc.

[0119] An auto pan key 265 is a key for consecutively operating pandrive in the region of an auto pan angle set up by using the menu key261. For example, if the auto pan key 265 is clicked, when the auto panangle is set up for 0 to 90 degree, then the pan drive is processed toconsecutively operate only in the region of 0 to 90 degrees.

[0120] A reset key 266 is used to reset the set-up information. A blockset-up key 267 supports to set up a desired block, when partly detectingthe movement of the image information displayed through the main imagedisplay window 81 after setting up the block for some region in the fullscreen. The set-up corresponding to the operation of the detailedphotograph manipulation key is performed by using the menu key 261.

[0121] If a next key 107 is selected again, the main frame replaces thescreen. On the other hand, since the main image display window 81 isoffered for a fixed size, a separation key 83 is used when the userwants to enlarge or reduce the size of the image.

[0122]FIG. 10 is a view showing a size variable separated image displaywindow offered when a separation key of FIGS. 7-9 is selected. As shownin FIG. 10, if the separation key 83 is selected, a separated imagedisplay window 183 is loaded. If the user adjusts an edge of the window183 by dragging or dropping the mouse 55 a, then the size of the window183 is adjusted, and the size of the image is also enlarged and reduced.At this time, the image is processed not to be displayed on the mainimage window 81.

[0123] The controller 72 operates to be corresponded to the manipulationof the keys described so far by controlling the module support unit 74,a display unit 73, and a transmitter 71 under the support of theoperating system 57.

[0124] The multichannel image driver 70 can be loaded as an inactivewindow when the user wants to use word processor by loading the documentedit application program.

[0125] Furthermore, there is a key 82 for setting up for the loadingposition of the frame 80 and 180 currently activated of the multichannelimage driver 70, when the user loads an application program besides themultichannel image driver 70. The following example is provided in orderto further explain the key 82 shown in FIG. 7. Let us suppose that thekey 82 is selected, and then a user executes a text editor program (suchas notepad, wordpad, or Microsoft Word). Among the several windows thatare open on the display screen of the computer, the upper-most windowbecomes the main frame 80, while the window immediately below theupper-most window becomes the window for the text editor program. Thus,the user can see all of the main frame 80, but can only see some partsof the text editor program window that are not hidden by the main frame80. The key 82 relates to a window viewing method which enables a userto edit a document (or perform other tasks) while the security mode isperformed as the main job.

[0126] As described so far, according to the multichannel imageprocessor and the security system employing the same, a desired securitysystem can be established if a record medium having the multichannelimage driver 70 installed in a computer, and connecting the multichannelimage processor 30 between cameras and the computer. Accordingly, therate of utility for resources will be increased, and a separate workusing the computer can be performed while watching an object, and thecameras can be remotely controlled.

[0127] Moreover, since the image information and the manipulatingapparatuses are offered together on the display device of the computer,the user can manipulate for watching or recording desired imageinformation by using an input device familiar to the user him/herself.
